Claims. (Cl. 222-483) .This invention relates to a dispensing device on liquid ontainers,fwhi ch devicehas a single filling, dispensing and cleaning opening which in the dispensing lposition is at the lower end of the conta-iner and which is provided with a screw closure, into whicha housing flange wthf dispensing means, which can be separately pulled out, and an air. inlet device which opens in response to subatmosphericpressure in the container, can be tightly and nonrotatably inserted so that it can be locked and closed.

yFor a container closure a closure memberV has already been. disclosed which is screwed intoy ya vscrew-threaded movably affixed on the outlet side withV a removable capnut whereas the dispensing cock does not have an air inlet opening directly associated with it.

The dispensing device for liquids according to the invention has the purpose of preventing a refilling of the container through the dispensing device so that liquid cannot be filled into the container through the single container opening Vunless the sealed screw closure is opened which contains the dispensing device. This prevents the filling of inferior products into the containerwhich is provided with a trade mark, the sign of a. firm or the.

like, and the sale of such inferior products as a highquality product.

In order to achieve the object stated the air inlet de-z vice is connected according to the invention to a separate conduit of the housing ilange, the valve member of the air Ainlet means isV controlled by a diaphragm of a dia-` phragm housing arranged in the container and the dispensing means provided in a manner known per se in a slide cylinder which can be pulled out has associated with it on the slide facing the` container a spring-loaded check valve which opens automatically in response to superatmospheric pressure in the container and which is inaccessible from the outside.

It isl known from experience that the inilowing air needs only a fraction of the cross-section required for the outow of a liquid, particularly of .thick oils. For this reason 'an exch-ange of liquid and air through a common duct requires a cross-section which is excessively large for the exchange of air Vand the control of which by the associated valve means involves diiiculties as far as the exchange of airis concerned. This is remedied bythe provision of' a plurality of conduits Vaccording to the invention to enable one valve member to be adapted to its purposebf controlling an air conduit small in diameter However, fthe dispensing atent il ,rate-md oce4, 196,0.

In Figs. 1,2, 1 is the `shell and 2 the end ofa barrel, which has no openings with theexception of a screwthreaded ring 3, Vwhich is `welded into the end `2 which is at the bottom in the dispensing position shown.

Through this ring the barrel can easily be cleaned and,A

filled.

The screw-threaded ring 3 has inserted therein a seall ing ring 4, in which a housing flange 5 is tightly screwed by means ofa screw ring 7. The housing ange 5 has. a socket 6 which extends into the barrel and together? with the stops 8 (Figs. 1, 6) provided at thev screw-f' threaded ring holds the flange 5 against rotation.- The screw ring 7 has two wrench.

Slidably ,mounted in cylinder 10, which is held against rotation by a groove 11 and a screw 12 (Figs. 2, 8 and 9). -The stop preventing the `removal of Athecylinder 10 is formed by a cylinder head 13, 13', which is rflattened at its top at 14 to provide space for the socket 6. In the front tpart ofthe cylinder A10 a cock plug 15 is incorporated. Thev opening 16 of this plug together with an opening 17 inv the cylinder forman angle cock. The opening 17 forms at the same time the discharge mouth (Figs. 1, 2 and 9).

The plug 15 has a sealing rim 18, which extends be yond the periphery of the cylinder. When the cylinder is inserted this rim engages a gasket 20 inserted ina groove 19 of the housingl iiange 5. This -will provide a seal against any leaks between the cylinder 10 and the housing ange 5 as well as between the cylinderli) andA the cock plug 15. The groove Y19 and the gasket 20.

extend below the screw-threaded ring 7, so that thegasket 20 is retained in position by this ring. i

In the axis of the plug a bipartite spindle 21,21' isarranged, the front part 21 of which is of reducedjdiameter in the plug 21 and is held against rotation by thef groove and nose 22 (Figs. 1 and 11) and as a screw: bolt is firmly and'tightly screwed by the spindle nut part121 the spindle 21. That end of the spindle whichprojects into the barrel has aixed thereto a slotted hub 27 by means of a clamp screw 28 to prevent the removal ofthe" y spindle andthe plug 15.

The hub 27 carries an arm 29, which carries Va segment- 30, to one end of which astrong leaf spring 31formed" like the segment is, eg., riveted (32). This spring tends,y to spring somewhat away Vfrom the'other'endjofthe@ segment (Fig. 4).v The segment and the-hub 27 are. .so,

adjusted relative to the cockV plug that when the; cock is claws 9, 9 for the application of a the housing flange Suis vthe slidev 2,954,905 t s f closed: (Fig. 6) the segment 30 with the stop 33 limits the rotation of the cock V15 in the closing sense and at' ythe same time the spring 31. snaps in at a rip 26' with which the bearing stirrup 26 is axed to the cylinder head @Fig- -111)'1. Thereby the plug is locked. The plug cannot be turned open until the slide cylinder'Y 130? ha'sbe'e'n sufficiently pulIed out (Fig. 27)? so that the yend of spring 31 snapped inv at 26' is urged back from a projection 35y at the socket 6 and is thus lifted from the ribv 2'6 to" remove the" lock; The socket 6 has a recess-34 (Figs. l and 2) so that aweb portion 6' remains at the end of the T-shaped socket. The projection 3'5 protrudes towards` this web portion to the full Width of the ange (Fig. 6). After the plug has'- been turned' open in' the clockwise sense when seen from the' rear 4as in Fig. 6, the segment Sti andthe spring 31 enter this recess to prevent the slide cylinder Il)` from sliding into the housingl ange before the' month of the plug opens. 'Ihe rotation of the plug t'o the fully open position is limited by the stop 33.

The spindle 21 extends outwardly and forms a head 21'". This spindle portion carries a handle consisting of al plate 37 with handle wings 39, 39 and the knobv These parts have a bore which accommodates the vspindle head 21". The spindle 21 is guided in a step formed at 40 in this bore. The step 40 (Fig. l0) hasv recesses 41 for receiving a' pin 42. A coil spring 43 (Fig. l) tends alwaysto urge the handle outwardly. If the handle is turned until the recesses 41 are in4 registry with the pin 42 the pin snaps into the recesses as far as the spindle head 21" and couples the handle to the spindle. This causes' the cock plug 15 to be coupled to the seg'- ment 30 so that the plug 15 can be operated by the handle' within: the segment stops 33, 33' vwhen the sliding cylinder has been pulled out.

'Iwo bolts 44 are also pivoted tothe cock plug 15 by means of two pins 45 (Figs. l, 1'1). These bolts have at their opposite ends pins 46, which engage grooves 47 extending spirally in the plate 37 (Fig. l0) of the handle. The pins 145 and 46 are so long that the bolts cannot fall out even if the handle is coupled to the pin 42 as described hereinbefore so that the handle snaps slightly out. On the other hand the bolts are still free' to move when the handle is forced inwardly (Fig. 1) and thus disengages the pin 42 so that the handle can be rotated independently ofthe pin and can be supported against the same. The rotation of the handle relative to the spindle 21 andthe pin 42 and consequently relative to the cock plug IS- causes the cam grooves 47 to rotate thebolts 44 outwardly or inwardly, depending on the direction of rotation; The angle of' rotation is finally limited by the engagement of the pins 46 in the grooves 47. As has already been mentioned the cylinder can only be pushed into the housing flange' 5 if the cock is closed` When the handle is coupled with the spindle the handle can only be turned to close as far as to the stop 33 in the arrangement shown in Fig. 6. The spring 43, however, is so strong that the handlecannot be pushed in tov become uncoupled unless the cylinder has been fullypushed in and the sealing rim -18 engages the seal 20. In this position the segment 30 together with the spindle 21 hasy been held againstrotation after the spring 31 has `leftthe. recess 34. Now thehandle canonly be rotated when it has been pushed in to become uneoupled. In thisf position the handle is locked by the boltpins 46 which engage toward the left when the bolt has been turned4 urge the entire piston system into engagement. Thereby f the sealing rim 18 is tightly forced againstthe gasket 20; 'Ille-Winge? disposed next to the c1aw'9 in thislocked "3 released.A

position has a bore 50 and the claw 9' has a transverse bore 51 for a seal cord 52 (Fig. 5).

Following the opposite sequence, dispensing is possible only if the'seal has been removed and the handle is unlocked by turning it to the left until it is coupled to the Vspindle 21,` 42, whereafter the handle together with the cylinder v10 is pulled out as far as to the stop and now opens the cock when the` segment 30 has been In this position the'mouthf 17 is sutiiciently spaced from the rim of the barrel to permit of a convenient dispensing (Fig. 2). v

Toprevent a filling oiliquidthrough the open cock a light plate valve 53i`sY guided on the spindle 21 and seals as a check valve at thevalve seat of the head 13'.'

The hollowed out valve hub 54 has.` in its interior a spring `55, which bears on theV one hand on the hub bottom 54 and on the other hand on a spindle collar 56 Y to urge the valve constantly on its seat. The valve weight and spring are so matched to each other that in position for use, whenthe spindle is in horizontal position,Y the spring pressure is just suicient to close the valve. When the barrel is inclined to dispose the valve plate above the seat the valve will always close and will remain closed in the operative position shown in `Fig. 2, unless the superatmospheric internal pressure, i.e., the liquid presrsure, is sufficient' to opening the valve. The valve can automatically open only in positions valve seat over valve plate but these are positions in which liquid cannot' be filled in unless a superatmos'pheric external pressurey is used, which will either endanger the vessel or, asi the valve s fairly unstable owing to the spring, the smallest ow can cause the valve to close'. The valve is mounted' at a low level in the housing so that it is very diicultly accessible through themouth andthe long cylinder and cannot beiufluenced from the outside. Even if it was possible to reach the valve with any means, the valve might only be pushed to close. y

For admitting'air, a separate air duct has been provided which is so controlled by a" valve and so guided that Iany inten-ference and soiling is prevented.

From the transverse bore 51 (Fig. 7) of Nthe rrightsure control valve (Figs. l, 2', 3), which consists of a screw-threaded socket `64 with neck 64' and housing 63 to which diaphragms 70 are tightly sealed by means of 'hoops 71 and screws 72 on both sides as in a drum. Seen in thedi-rection of the socket axis 61 the housing ring, is provided iirst (in operative position according to Figs.

l, 2) with a valve seat 63", the valve plate 67 of which with gasket y68 is mounted by means of a spindle 66 guided on transverse arms 65, 65'. To increase the pistony effect the diaphragms, which consist preferably ofA buna, are stiffened with plates 74, which are screwed` fast with soldering head screws and collar nuts 76. The

collar nuts are engaged'by slotted levers 77, which are( pivoted bya hinge pin 78 to an offset plate 79k having a neck 80, which is mounted on the spindle 66 and bearson the valve plate they gasket 68 to retain the same. The

slotted levers 77 carry thumb levers 81 which bear oni `soon as the pressurein the valve yhousing exceeds that in the barrel both diaphragms oppose thevspring forcev in the same sense and open the valve.

It is essential to prevent the air conduit from becoming drowned. Forl this purpose the valve must safely rpreclude a penetration of liquid. For this reason a trigy ger 82 (Figs. l, 2, 3) is provided, whichis mounted by trol valve in such a manner that the shaft 84 forms a U-shaped rod 84 the limb 84" of which engages a push rod 85, which is pivoted by means of pins 86, e.g., on a bearing bracket 87, to the slide cylinder 13. An adjusting member, e.g., an adjusting screw 88, enables the trigger 82 to be set so that the valve will be positively sealed when the slide cylinder is pushed in and locked (Fig. 1) whereas in the operative position the trigger 82 lifts from the valve plate so that it does not obstruct the function of the control (Fig. 2).

As the liquid pressure adjacent to the bottom would obstruct the function of the diaphragm-type air valve the neck 64 of the valve housing and with it the linkage 84, 85 must be correspondingly longer in practice than shown in Figs. 1, 2, 3, 4 so that the necessary pressu-re drop between the diaphragm housing and the surrounding lfluid can build up without hindrance and liquid'can be discharged at a sufficiently high rate. The dash-anddot lines 111, 111' (Fig, 2) indicate approximately the path described by the housing 63 of the air control valve during the insertion and removal of the dispensing device (only possible in the dispensing position, Fig. 2).

The barrel can only be iilled and cleaned when the dispensing cock has been entirely removed after the removal of the screw ring 7. To prevent this from being done by an unauthorized person the left-hand claw 9 of the screw ring is also bored through and provided with a screw thread 91 (Fig. 7) anda conical groove 109'. A screw 93 having a shank 92 could be turned into this -bore and the end 90 of this screw could engage a groove 108 (Fig. 8) of the housing flange 5 (Fig. 8). As the flange is held against rotation by the stops 8 of the screwthreaded ring 3 the screw ring 7 'cannot be rotated or be turned out until the screw has been screwed back.

The conical groove 109 serves to enable the forcing in of a seal 110 for sealing the closure. The uninjured seal ensures the unfalsied contents of the barrel.
